Flashcards in Chapter 2 Truck Company Response, Placement, and Operations Deck (43):
1

What is the biggest single factor in total stopping distance?

Speed

2

What are the seven steps of visual awareness?

1. Know your blind spots
2. look ahead
3. get the total picture
4. constantly move your eyes
5. maximize your perimeter space
6. allow sufficient following distances
7. make sure they know your intended actions

3

Effective fireground operations center around how many incident commanders?

One

4

Who should determine the initial placement of apparatus at an incident?

The first-in officer

5

When comparing the placement of engine and truck companies, which normally offers the most flexibility when spotting to a structure?

Engine companies

6

What are the two advantages of having responding companies approach an incident from different directions?

The companies will collectively see more sides of the building as well as primary and alternate sources of water

7

What are three key factors that can affect the ability of an aerial device to reach an objective?

1. Setback
2. height of the objective
3. length of the aerial device

8

What is the practical definition of maneuverability as pertains to apparatus placement?

Turning radius

9

Why should an aerial device be spotted to the corner of a building if possible?

to reach two sides,
the aerial device won't be place over horizontal openings,
the corner is the strong area of construction,
it is out of the potential collapse zone,
and the aerial can be used as a potential defensive exposure protection tool.

10

What is the definition of target area as pertains to aerial device operations?

The area that can be reached by an aerial device

11

Who has given the fire service the right-of-way in most cases

state laws

12

Who can be held accountable for unsafe operation of a fire apparatus?

Driver and department

13

What 2 factors primarily save time in an actual response?

1. Getting to apparatus quickly
2. Knowing your district

14

If speed is doubled, what happens to perception-reaction distance?

Braking distance?

perception-reaction distance is doubled

Braking distance is 4x

15

While driving, the "total picture" contains what 3 basic elements that affect judgment and actions?

1. vehicles and obstacles
2. warning devices
3. ability to predict actions and events

16

As pertains to responding code in an apparatus, what is a Offset Formation?`

a distorted V.

Lead apparatus close to center line,
2nd apparatus to far left or right
3rd apparatus to far left or right, opposite of the 2nd

17

Where do most accidents involving emergency apparatus occur?

intersections

18

How much more stopping distance is required to stop on wet concrete as opposed to dry concrete?

35 to 40 percent more stopping distance.

19

What 2 things make a good driver?

Good attitude
Good judgment

20

Obstructions such as buildings, hills, heavy brush can reduce siren audibility by how much?

2/3rds

21

What warning device should not be used in lieu of a siren?

air horn

22

A lack of initial direction will usually result in what?

freelancing

23

What does the success of an operation depend on?

Communication

24

What is a Size-up?

The estimate of a situation made by the officer in charge, through whom it is determined what to do and how to do it.

25

What should a Size-up include? (5)

Address
Observed conditions
Initial actions
Instructions to incoming companies
Requests for other resources

26

What is apparatus placement dictated by? (2)

Incident priorities
Vehicle function

27

With moderate setback, how far can a 75 foot Aerial device reach?

The roof of a 4-story building

28

How high can a 100 foot Aerial device reach?

Roofs of 6 to 8 story buildings

29

An Aerial device is often "only" considered for use on structures that are how tall?

3 or more stories

30

As the Angle of Inclination increases between the ground and the aerial device, what happens to the strength of the aerial device?

it increases

31

On uneven terrain, which side of the aerial device should raised first?

Low side jacks first

32

With the advent of Maxi brakes, the purpose of chock blocks has switched from what to what?

from preventing the vehicle from rolling to distributing load-carrying capacity across more tire surface

33

How far should you keep the aerial device from electrical wires?

10 feet

34

How many feet should be clear behind a truck? Why

30 feet. Ground ladders

35

Where do you place the aerial ladder when placing to a window or fire escape balcony?

top rung flush with the sill or railing

36

When approaching an objective on a hill, do you want to be uphill or downhill? Why?

downhill. Increases the angle of Inclination

except when the aerial wont reach the objective.

37

What can you look for to determine the height of a parapet?

attic vents
rafter tie plates
scuppers

38

What should be the capabilities of a platform aerial device?

Lift 500 lbs at the tip WHILE flowing 1,000 gpm of water in any position

39

What should be the objective of extending a ladder over an objective?

extend it far enough to be seen easily from the roof

40

What does a pinnable waterway let you do?

allows the ladder to be extended without the waterway and monitor, facilitates closer placement of the ladder

41

How far above an objective should an aerial ladder be placed? Why?

4 to 6 inches

may foster building collapse
may weaken the ladder

42

NFPA 1904 requires what of new aerial ladders and platforms?

requires all new aerial ladders and platforms to have or exceed a rating of 250 lbs at the tip at full extension and be able to operate in any position

43
